FAQs About Scalloped Potatoes

You can make scalloped potatoes healthier by replacing high-fat, high-sodium ingredients. Use unsalted vegetable stock or low-fat milk instead of heavy cream, flavor with herbs and spices instead of excess salt, and use heart-healthy fats like olive oil instead of butter.

Potatoes like Yukon Gold, red, or sweet potatoes are great for a heart-healthy diet. They are rich in potassium, which can help manage blood pressure, and are a good source of fiber. The key is to prepare them without a lot of salt, butter, or cream.

The main difference is cheese. Traditional scalloped potatoes are baked in a creamy sauce (often milk or cream), while potatoes au gratin are made with cheese and often have a topping of cheese or breadcrumbs. This recipe is a variation on scalloped potatoes, using stock instead of cream.

To prevent watery scalloped potatoes, ensure your potato slices are not too thick, as this can prevent them from cooking evenly and absorbing the liquid. Also, allowing the dish to rest for at least 15 minutes after baking lets the starches in the potatoes set, which helps thicken the sauce.

More Healthy Potato Side Dishes

Often misunderstood, potatoes are a fantastic source of essential nutrients like potassium and vitamin C, making them a smart choice for any balanced diet. Their incredible versatility means they can be roasted, mashed, or baked to create the perfect healthy and satisfying side dish for any occasion.

What to Serve with Scalloped Potatoes

Finding the perfect main dish to complement your heart-healthy scalloped potatoes is easy with these flavorful dinner ideas. The creamy texture and savory flavor of the potatoes pair beautifully with a wide variety of lean proteins, from baked fish and grilled chicken to slow cooked pork tenderloin.

Troubleshooting Common Issues with Scalloped Potatoes

  • Potatoes are Undercooked: If the top is browning too quickly but the potatoes are still firm, cover the dish loosely with foil and continue baking until a knife can be easily inserted into the center. Slicing potatoes into thin, uniform 1/8-inch rounds is key to even cooking.
  • Dish Seems Dry: Different potato varieties absorb liquid differently. If the dish looks dry during baking, you can add a few extra tablespoons of warm, unsalted vegetable stock around the edges.
  • Onions Won't Caramelize: Caramelizing onions takes time and low, steady heat. Do not rush the process by turning up the heat, as they will burn instead of becoming sweet. Cooking them slowly for the full 45-60 minutes is essential for the best flavor.

Ingredients

Recipe yields 8 servings

Directions

  1. Step 1

    Preheat oven to 400°F. Generously grease a 1.5-quart casserole dish or a large deep cast iron skillet with nonstick cooking spray. Set aside.

  2. Step 2

    In a large sauté pan, heat the olive oil and butter over medium heat. Lower heat to low, add the onions and sprinkle with ⅛-teaspoon salt; cook, stirring frequently, for 45 minutes to 1 hour to caramelize them. Add ½ tablespoon of thyme and garlic about halfway through caramelizing process. When the onions are done, pour them into a fine mesh sieve to drain the oil-butter sauce into a small bowl; set aside.

  3. Step 3

    In a small mixing bowl, combine the remaining thyme, dried sage, black pepper and remaining salt. Spread a layer of potatoes on the bottom of the prepared baking dish, followed by a layer of caramelized onions. Sprinkle with the herb mixture. Continue layering, ending with a layer of potatoes.

  4. Step 4

    Pour the vegetable stock over the top of the potato casserole, followed by the reserved oil-butter sauce. Bake for 50 to 60 minutes, until the top is golden brown and the potatoes are crispy around the edges. Allow to rest for 15 minutes. Serve warm and enjoy!

Serving & Storage Tips

  • Make Ahead: You can assemble the entire casserole a day in advance. Cover it tightly and store it in the refrigerator. You may need to add 10-15 minutes to the baking time if cooking from cold.
  • Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
  • Reheating: For best results, reheat individual portions in the microwave or place the entire casserole dish back in a 350°F oven for 20-25 minutes, or until heated through.

Ingredient Substitutions

If you are not strictly dairy-free, you can substitute half of the vegetable stock with an equal amount of low-fat milk or evaporated skim milk for a creamier result.

For a tangy, creamy alternative, you can whisk ½ cup of plain, non-fat Greek yogurt into the warm vegetable stock before pouring it over the potatoes. Do not boil the yogurt.

To make this a main course, add a layer of thinly sliced, low-sodium cooked ham or chicken between the potato layers.

For a cheesy flavor without the fat and sodium, sprinkle one to two tablespoons of nutritional yeast between the layers along with the herb mixture.
